TV watchdogs in the U.K. are assessing whether Bbc bosses risked breaching broadcasting regulations by airing footage of disgraced pop star Gary Glitter during a primetime show.The glam rock icon, real name Paul Gadd, was sentenced to three years in prison in Vietnam for sexually abusing two girls aged 10 and 11, and since his release in 2008 he's been a figure of hate in his native U.K. On Saturday night (12May12), footage of Glitter singing his track It Takes All Night Long in his 1970s heyday on TV show Top of the Pops was broadcast by the Bbc - and the controversial move prompted a handful of complaints. Officals at the Office of Communications (Ofcom) are now assessing whether the complaints warrant a full investigation. An Ofcom spokesman tells WENN, "We can confirm that we have received complaints which we are currently assessing but not yet investigating." A spokesman for the Bbc stood by the decision to air the clip, insisting it would be "inappropriate" for the corporation to "rewrite history".
